SAP ERP 物料主数据同步外围系统

 物料主数据集成在很多项目是比较常见的需求，在做系统实现之前我们需要明确涉及的业务流程和需求范围，并且对每个系统的业务边界进行明确：

     如果是从SAP ERP 向其他系统推送数据，并且实时性要求高的情况下，我一般倾向于在增强出口里实时抓取系统新增，或修改，或删除的数据给外围系统。这里以物料主数据的BTE增强，增强事件00001250为例：

第一步：事务代码FIBF

第二步：点设置->产品->客户

 第三步，配置事件、产品和函数的对应关系。点击设置->发布/订阅模块->客户的

 ZSAMPLE_INTERFACE_00001250，需要先复制标准函数SAMPLE_INTERFACE_00001250

 代码示例：
